RE: Ontology editor + why RDF?

 

A straight-foward "porting" is always wrong, or lack of the comprehension of
difference between RDF and other exiting technologies.  RDB and XML schema
contains implicit semantics that should be explicitly expressed in RDF.  

 

[VK] Making the underlying data model constraints in the RDF graphs is what I
meant by extra semantcis - In the relational model, that would correspond to
primary, foreign keys, functional and inclusion dependencies, etc.... Some of
this would likely require OWL...

 

Even so, why does it have to have new semantics?  The first thing first is to
ground "things" on to the web.  Connecting a URI with another is as easy as it
gets, the same can not be said about connecting a particular row of one DB to
another.  The added value is not "all" about semantics, it is interoperability.

 

[VK] Exactly my point! The added value is all about cross-linking, which comes
from the web infrastructure (URIs) and not from semantics!
